I bought this amp a few years ago as part of a package deal. I hooked it up before purchase and it worked, but as soon as I tried to use it for real it popped 4 mosfets on the input side. Included are some pics of the board and of the blow mosfet, does anyone know a good place to buy them? This is a gorgeous amp and I would love to get it going again.

In the first pick are those the diver transistors, and in the second pic are those the gate resistors? What I think are the gate resistors are also a little burnt looking but I can't seem to find them on the net to find out what they are.

I found a resistor that may be a problem, it is the one closest to the edge of the board. It seems to have a hot spot on one of the gold strips as shown in the picture. To power it up I should re mount the board to the heat sink right?
